Crankset question

I own a Kona Hoss and ride all kinds of terrain. I'm 6'0, 275lbs, the bike works great for me but I'm wondering about a new crank. Would it make sense to put a Saint 3 on my bike? I don't race, I like a good pace but more than anything I like something STURDY.

Thanks... just wondering what X-type is sorry for the dumb question just a newbie.

"X" is short for "external". The bearings are located outside the bottom bracket shell. That just means that the bearings are larger and longer lasting. But the side benefit is that the crank itself is stiffer. The interesting thing about the x-types is that they seem to hold together much better than ISIS. I had an ISIS set up that kept coming loose every thirty minutes, even after squirting red loctite all over them. I finally managed to crank the end bolts down hard enough and used enough loctite that they stayed put for a few weeks. In the end, they still managed to work loose. But this has never happened with my x-type crankset.
